Following on from the previous HD 6000M series (known as Vancover), the DirectX 11.1-compatible Radeon HD 7000 series has three parts - the Radeon HD 7700M (Chelsea), 7800M (Heathrow) and 7900M (Wimbledon).

The three chips boast Eyefinity and HD3D support as well as HDMI 1.4a. There's also AMD Enduro technology, that drops the power consumption down to less than 1W when the graphics chip is not being used.

The top-end HD 7970M is very similar to the AMD Radeon HD 7870 desktop part in terms of spec aside from the clockspeed – the part has 1,280 Graphics CoreNext stream processors and 2GB of GDDR5.
